Do you suitably tickle the clock rate definitions for some of the registers?
IIRC (having looked into this stuff in FreeBSD), enabling turbo mode sets
the clock to double-rate, needing changes to some of the registers like ACK
timeout, slot time, SIFS, etc., which operate on clock-ticks rather than
microseconds.
